Hi, Facing issue with DB query node while using simple sub-query.

select TOP 12 ID from (select ID from PROJECT WHERE ID=ac!prjId )_result

While validation showing error:

"Errors
There was a problem during the validation of the SQL statement with the database

The SQL Query is invalid, com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword \\'WHERE\\'."

If i remove inner "WHERE ID=ac!prjId" condition it works fine. Appian 7.6 + MSSQL Server2008 + Jboss 6.2

Thanks, Ritesh

Maybe it is cause by the underscore after the closed parentheses?

Hi Marco,
It is an integer variable but it is created externally i.e. once query validated, it should be there in input section.

Have you tried to use this statemnt directly on sqlserver substituting the value of the ac! with a value of type integer that you know exist? it works correctly?

Hi Marco, Thanks for reply! Yes, it works, it works even with more complex query. In fact we have same query in one of our process model, working fine. Now after upgrade, when we are trying to update process model it does not allow the same query to validate. Thanks.

try with this:
select TOP 12 ID from (select ID from HSE WHERE [AppianHSE].[dbo].[HSE].ID=ac!oldID)_result substituting [AppianHSE].[dbo].[HSE].ID with [PROJECT].ID

"The database returned ARV's that may not be supported. Message: Incorrect syntax near \\'substituting\\'."

ok last tips:
-select a custom datasource
-select the source type
-enter the ip
-enter the username and the password
-use this statement substituting [AppianHSE] with the name of your database and [HSE] with [PROJECT], remember to use [dbo]
select TOP 12 ID from (select ID from [AppianHSE].[dbo].[HSE] WHERE [AppianHSE].[dbo].[HSE].ID=ac!oldID)_result

Hi Marco,
:) It works. Thanks a lot. I feel stupid when i copied your last statement as it is :(. So, finally with

select TOP 12 ID from (select ID from PROJECT WHERE [appian_sandbox_new].[dbo].[PROJECT].ID=ac!oldID)_result

OR

select TOP 12 ID from (select ID from PROJECT WHERE [PROJECT].ID=ac!oldID)_result

queries it is working. I did not create custom datasource instead used the same existing datasource name.

Thanks again, Ritesh
